UNSOLVED
Uncached Speed Extremely Slow
I have a Dimension 4600, P-4 2.66 w/ 1 gig of RAM, OS XPHome. My PC Pitstop test says that I have "Unusually low disk performance" with uncached speed of 1.99 on "C" and 1.52 on "D". Their comparison says I should be getting 13.65.
I have been unable to use most of PC Pitstop's TIPs to fixing the problem, IE:
"Delete uneeded files & Defrag" - Did that, no improvement.
"Disable background software" - Did that, no improvement.
"Enable DMA" - I have Enable DMA if Available checked, but it says its using IPO (or whatever its label is - can't remember).
"Update Driver" - I can't find a driver update at Western Digital website, Windows says I have the latest.
"Make sure write cache is enabled & turn off quied mode" - I can't find a utility to assist me in this process"
I have read all the threads in the Forum on this issue that I can find, and other than the ones that are too technical for me to follow, I can't figure out how to fix this problem.
Any help would be appreciated.

Go into BIOS and verify that the primary and secondary IDE channels are set to AUTO detect. Save and reboot PC. Go to Device Manager and remove the Primary AND Secondary IDE channels. Windows will reload the drivers. Go back to Device Manager and set Devices 0 and 1 of EACH IDE channel to use DMA mode if available. Reboot PC and verify that all devices are operating in DMA mode.

I think that im in a similar situation; your feedback is greatly appreciated. I have a brand new 4600 with an 80gb maxtor drive, i routinely run pcpitstop and one day my uncached speed went from around 5 down to 2mb/s. I have done all the fixes posted; reinstalling the OS, defrag, reinstalling the ide channels etc..... I just ran HD tach and came up with the following numbers:
access time : 22.6ms
read speed:
max 60.5
min 23.8
avg 49.1
CPU utilization: 6.1%
are these numbers any good? Am i worrying for no reason? do you think that there is just a glitch when running pcpitstop with this particular drive? thx
